ALE has installed a curved steel bridge, weighing 2,100 tonnes, between two hotel towers in Baku, Azerbaijan.
The bridge was installed at a height of 120 m and will link the two towers of the La Luna hotel.
Strand jacks were prepared on bespoke jacking beams, which were then mounted on each of the towers, 138 m above the ground. ALE’s method enabled the linkspan bridge, measuring 72 m x 20 m x 22 m, to be constructed entirely at ground level.
Dan Kempin, business development manager – offshore services at ALE, explained: “Civil engineering projects often pose unique challenges. On this occasion, we brought across our offshore strand jacking expertise, allowing us to work in confined spaces, with restricted lifting options and using a micro-step-by-micro-step methodology.
“This area can experience wind speeds of up to 80 km/h and therefore we knew our lift monitoring solution had to be optimised for immediate reporting on wind speed and load displacement. The bespoke design of our strand jack monitoring process ensured ALE could continue to operate within a greater window of wind speeds, as we could monitor the real-time wind effect.”
ALE will be performing a further two lifts for the project.
